Part 6: Better long running custom Firmata functions.Part 5: Custom Firmata function called by Windows 10 IoT.Part 4: Add virtual Arduino ports to your UWP app.Part 3: Use Bluetooth between Win 10 UWP and Arduino.Part 2: Using I2C between Rpi Master and Arduino Slave.Part 1: Using I2C to connect two Arduino Nano’s.While (Wire.This is part 1 of a series of blogs about device communication between Arduino, RaspberryPi etc: Wire.requestFrom(8, 1) // request 1 byte from slave device #8 Wire.endTransmission() // stop transmitting Wire.write('Master value : ') // sends these bytes

Wire.beginTransmission(8) // transmit to device #8 Int y = analogRead(A1) //Read from A1 & Save to value Wire.begin() // join i2c bus (address optional for master)

Now copy the following code and upload it to Arduino IDE Software. Here is a simple step-by-step guide on “ How to Add Libraries in Arduino IDE“. Installing Librariesīefore you start uploading a code, download and unzip the following libraries at /Progam Files(x86)/Arduino/Libraries (default), in order to use the sensor with the Arduino board. Here is a simple step-by-step guide on “ How to install Arduino IDE“. It’s a primary, two-wire interface for linking electronic devices and exchanging data.įirst, you need to install Arduino IDE Software from its official website Arduino. What is I2C Communication Protocol?Ī common and frequently used serial communication protocol, I2C (Inter-Integrated Circuit), lets devices like microcontrollers communicate and share data with one another. So, there are many other ways to use two Arduinos together, depending on the project and its objectives. By linking Arduinos, you can also construct a network of wireless sensors. One Arduino could be the master controller, sending instructions to other Arduinos that run different motors or sensors. Each Arduino in a distributed system can have a specific job. In this tutorial, we Connect Two Arduino Boards Using I2C Communication Protocol!Īs a beginner, the question might arise in your mind: why connect two Arduinos? Because multiple Arduinos can increase your project’s possibilities for example, one Arduino may control a display while another, motors or sensors.
